Centrifuge
Henry,
I placed an order for the OC20 from Dieselcraft.com
It was all totaled around $319.00 and change including shipping.
It's a big nut up front and I thought about not doing it but the time savings and the fact that you don't have to mess with filters weighted significantly in my final decision.
I will still filter the oil to get the big stuff out prior to it hitting the centrifuge, but this is really no big deal, and minimal impact to the process as compared to when using filters near the 5 or less micron range.
Some thoughts into the decision process.
1) Time
2) Quality of the finish product
3) Cost ROI (Return on Investment) of fuel in Cleveland anyway was $4.80 /gal last I filled up in my VW TDI
4) TCO (Total Cost of Ownership) over time if you consider buying filters, cost of shipping, trips to the store and so on.
My goal is to keep this as simple as possible. I am going to mix the oil with gas prior to spinning it through the centrifuge, clean them both up prior to hitting the deuce.
This eliminates the need to heat the oil to thin it out prior to spinning, and all the related electrical and plumbing to do this. (keep in mind, if your cleaning strictly oil, you have to heat it to thin it.)
The other thing I am toying with is using my current air compressor to control the OC20 so I don't over drive it. If you read on the OC, it needs a 2.2gpm pump at 90psi with a bypass valve to control how much oil is sent into the process. Actually 90PSI is recommended, depending on the pump you get, @90psi, you can still have too much volume flow and flood the centrifuge.
I can't prove this yet, but if I can take the mechanics out of the front end process and have a high degree of control over the input, I am pretty sure I can make this work and have the ability to play with the variables to optimize the performance and quality of the product.
Worst case I have to purchase a pump that they recommend. If you shop around, you can find pumps and motors to their specs for about 150 bucks less.
The other thing to keep in mind is just the fun factor.... This is fun, measured by the eye roll count received by the wife.
